The HTC Evo 4G is one of the few smartphones to have an HDMI-out port, letting you connect your phone to your HDTV and display photos and videos in high definition. (You can read CNET's hands-on experience with the Evo 4G's HDMI-out here.) To do so, you will need a compatible cable, such as the Amzer Micro HDMI cable. The 1-foot cable goes for $7.95; Amzer also offers a 5-foot cable and a 15-foot cable. Regardless of what length or brand you're looking for, just make sure that it has a Micro-HDMI connector (or Type D), so it fits with the Evo 4G's port.
